My eldest is 18, almost 19, his girlfriend is 19.
She found out she was pregnant when they were in year 11 with her then boyfriend, DS supported her as the actual father didn't want anything to do with her or the baby. DS also supported her when the baby was born and she is now almost 2.
DS and his girlfriend have been in a relationship for almost a year, and recently the little girl has been calling him daddy. Except, DS isn't her dad.
AIBU to not want him to be her ‘dad’ especially as he's so young!
